Table 11. Morphometrics of Acestrocephalus stigmatus. Standard length is expressed in mm; measurements through head length are percentages of standard length; last four entries are percentages of head length. Specimens are from MNRJ 28718 (holotype), 17610 (paratypes), MZUSP 10422, and 62846 (paratypes).
